MAGNETIC STUDY OF THE NORTHEASTERN SIDE OF THE AVAWATZ MOUNTAINS, SOUTHERN DEATH VALLEY

During the past year, average total field and gradient magnetic data have been collected in the alluvial fans of the northeastern Avawatz Mountains in southern Death Valley. The purpose of the study is to define structural trends associated with the eastern termination of the Garlock fault zone. A secondary goal is to define the extent of intrusions in the subsurface of the region that may define offsets on the Southern Death Valley fault zone. Approximately 200 data points were collected along the mountain front. Approximately 50 of those data points included both average total field and gradient data. Elsewhere, only total field data were collected. The data were collected over a time span of approximately one and a half years. The data are now being reduced and modeled to determine what the structures in the area are. This analysis is expected to show the orientation of faults in the subsurface and the extent of intrusions in the region.
